Nanometer light guide plate, method for preparing nanometer light guide plate and display device

Abstract

The invention relates to the technical field of light guide plates, in particular to a nanometer light guide plate, which comprises a light guide plate body, uniformly dispersed nanometer light scattering particles are doped in the light guide plate body, and nanometer dispersion slurry and an antioxidant are further arranged in the light guide plate body, wherein the upper surface and the lower surface of the light guide plate body are respectively provided with a nanometer reflection enhancement layer, and one side of each nanometer reflection enhancement layer, which is far away from the light guide plate body, is provided with a protective layer, and the invention also provides a method for preparing the nanometer light guide plate and a display device. The nanometer light guide plateis high in light conversion rate, uniform in light, safe and environmentally friendly; the product can be cut into required sizes at will and is suitable for indoor and outdoor use, and the applicability of the product is enhanced; the surface is precise, double-sided light guiding is achieved, products with small thickness can be used under the condition of the same brightness, and cost is saved;any point light source and line light source can be used for area light source conversion, the process is simple, manufacturing is convenient, and application and popularization are facilitated.

Description

technical field [0001] The invention relates to the technical field of light guide plates, in particular to a nano light guide plate, a method for preparing a nano light guide plate and a display device. Background technique [0002] The light guide plate is made of optical-grade acrylic or PC board. It uses high-tech materials with a very high refractive index and does not absorb light. Laser engraving and V-shaped cross grids are used on the bottom of the optical-grade plate. Engraving, UV screen printing and other technologies are used to print the light guide points, and use the optical grade plate to absorb the light emitted from the lamp to stay on the surface of the optical grade plate. When the light hits each light guide point, the reflected light will spread to all angles , and then destroy the reflection condition and emit from the front of the light guide plate. Through light guide points of various densities and sizes, the light guide plate can be made to emit ...

AI Technical Summary

Problems solved by technology

[0003] The light guide plates widely used at present are mainly prepared by injection molding, photolithography, laser engraving or printing. Among them, the equipment used in the injection molding method is complicated, the price is high, and the production cost increases; the light guide plate made by photolithography The surface roughness is not good, and the loss of light energy is relatively large; although the laser engraving method can accurately control the depth of the scattering structure, the efficiency is very low, which is not convenient for mass production; the light guide plate made by the printing method cannot be cut at will. There are application defects

At present, the thinnest thickness of the light guide plate produced is 2mm. The larger the size, the thickness must be increased accordingly in order to ensure the brightness, and the light guide effect is correspondingly poor. The thickest light guide plate does not exceed 20mm. Sometimes it is often difficult to meet the needs of the market, and its structure and preparation method need to be further improved
